The .pro format

Files of type .pro (to be found in /data/annot/text/pro1 and /data/annot/text/pro2/ on the annotation DVD) comprise the prosodic annotation, which is based on the orthographic transcription in the .ort file. The .pro files are in ShortTextGrid format and can be produced, changed or viewed by means of the PRAAT software. For a description of the ShortTextGrid format, see the description of the .ort format. The format contains time markers that are independent of the time markers in the orthographic transcription. For each speaker exactly one tier is envisaged. The tier name is the same as the speaker code. As opposed to the .ort file the .pro file does not have a COMMENT or BACKGROUND tier. For each .pro file there is also an XML variant in the so-called .prx format. These files can be found in /data/annot/xml/prx1 and /data/annot/xml/prx2 on the annotation DVD.

Apart fromt he characters and symbols that are used in the .ort format in the prosodic transcription use is made of an extra symbolset to indicate prosodic phenomena:

`\|\|`	Represents a strong break.	`ja dat weet ik \|\| maar wanneer` `ik ben bij de politie\|\|commissaris ontboden`
`\|`	Represents zweak break.	`jan \| en ook piet` `dit is werkelijk on\|ge\|looflijk`
`^`	The vowel part of a prominente syllable is indicated by the '^'-symbol on either side.	`^i^k ben thuis` `het is ^eeu^wen gel^e^den`
`%`	An unusual lengthening of a sound, without giving prominence to the syllable, is indicated by means of the percentage symbol ('%')	`%ja% \|\| maar dat is verk^ee^rd` `hij is pas viere%n%d^e^rtig`

Strong and weak breaks ('|' and '||' resp.) are enclosed between blank spaces unless they occur word-internally.
